9 Claims.

This invention relates to an advertising display device and has for itsprincipal object the provision of a highly efiicient mechanism whichwill successively display a series of advertising cards to produce acontinuously changing display of advertisements, and which can beoperated either by hand or by means of an electric motor.

Another object of the invention is to provide a motor operated devicewhich cannot damage the cards or displays even though the machine maybecome clogged. r

Other objects and advantages reside in the detail construction of theinvention, which is designed for simplicity, economy, and efliciency.

These will become more apparent from the following description.

In the following detailed description of the invention reference is hadto the accompanying drawings-which form a part hereof. Like numeralsrefer to like parts in all views of the drawings and throughout thedescription.

In the drawings: I

Fig. 1 is a perspective view of the improved advertising display deviceenclosed in a suitable ornamental housing. r

Fig. 2 is a vertical section therethrough, taken on the line 22, Fig.1.

Fig. 3 is a front view of a motor operated operating mechanism with theenclosing housing removed.

Fig. 4 is a vertical section through a hand operated form of theinvention.

Figs. 5 to 8 inclusive, are diagrammatic views illustrating theoperation of the card changing mechanism.

Fig. 9 is a fragmentary vertical section taken on the line 99, Fig.4.

Fig. 10 is a detail section through the card changing mechanism, takenon the line l6l6, Fig. 7. s

The operating mechanism is supported from a base plate In upon avertical post I I and a vertical guide I2. A pack of cards, illustratedat [3, car- 45 rying the advertising to be displayed, is carried in aninclined card holder I 4 supported from the base plate upon suitablepedestals l5. A glass plate 33 covers thefront of the card holder.

The device operates to continuously lift the lower or rearmost card ofthe pack anddeposit the same on the front of the pack. i

The changing of the cards is accomplished by means of a tubular slide I6which rides vertically on the guide l2. The slide member 5 is lifted bymeans of a cross head I! also slidably mounted on the guide member l2.The cross head may be lifted either by hand or by a motor drivenmechanism. For hand operation, a hand lever I8 is pivoted, as shown at[9 between the pedestals l5 and extends rearwardly through the guide I2beneath the cross head l'l. Thus, when the forward extremity of thelever is depressed, the rearward extremity thereof will act to lift thecross head and the tubular slide" l 6.

As the slide rises, the rearmost card of the pack is pushed upwardly byfrictionalengagement with the edge of a rubber pushing block 22 which issupported from the tubular slide upon suitable leaf springs 23. Agripping plate 24, pivotally mounted upon a hinge clip 25 extending fromthe slide I6, carries an L-shaped weight 26 which bears on the cardsahead of the rearmost card to prevent the former from moving upwardlywith the latter, as shown in Fig. 5. After the rearmost card has beenpushed upwardly from the pack, the weight 26 will swing downwardlyagainst the front thereof and the springs 23 will cause the block 22 toclamp the card thereagainst, as shown in Fig. 6. The slide continues torise carrying the card with it until the card is clear of the pack, asshown in Fig. 7. On its way upward the gripping plate snaps beneath aratchet extremity 21 on a releasing spring 28, as shownin Fig. 7.

. The slide l6 now moves downwardly, as shown in Fig. 8, causing thegripping plate 24 to strike the ex'tremity2l of the releasing spring 28.As the slide continues, downward the gripping plate is held so that thecard is released and forced forward by the springs 23 to drop onto thefront of e the pack, as shown in Fig. 8. As the slide I6 continuesdownward, the gripping plate 24 snaps from position in the'ratchetextremity 21 and again drops down on the top of the pack of cards, asshown in Fig. 5, to repeat the cycle of operation. The gripping platecarries a rubber contact cushion 42 to cushion its contact with thereleasing spring 28.

Means are provided to adjust the device for various cardthicknesses, andit can also be adjusted to pick up one or more cards, by means of anadjustable backing plate 29 which is supported on adjusting screws 30,from the back of the card holder l4. By adjusting the screws 30, theposition of the rearmost card in relation to the. lifting mechanism canbe varied. The releasing spring 28 is suspended from a top frame member3| having sockets 32 for receiving the upper extremities of the membersII and I2.

Thus, it can be readily seen that if the slide .Worm wheel 31.

member 1 6 moves upwardly, it will first cause the block 22 to push therearmost card above the other cards then the gripping lever 24 willswing downward to bring the weight 25 against the card to hold itagainst the block 22. As soon as the lower extremity of the lifted cardpasses above the pack of cards, it will snap forward to the position ofFig. 7 at which time the slide member will start downwardly. The firstmovement will release the weight 26 allowing the card to fall to thefront of the pack.

In the motor driven form of the device, a connecting rod 34 is connectedat its lower extremity with a pin 35 secured to the cross head 11. Theupper extremity of the connecting rod is hingedly mounted on a crank pin35 extending from a The Worm wheel 31 is journalled on a suitable axlemember 38 on the re'ar'frame member II and is rotated from an electricmotor 39 through the medium of a suitable transmission worm 4i).

It is desired to call attention to the fact that the downward movementof the slide member l6 and its associated mechanism is accomplished bygravity only. There is no positive push from the motor itself. Thus ifany of the cards become caught above the pack, they will not be crushedsince they simply act to support the slide member while the motorcarries the cross head ll downwardly under power.

The entire mechanism may be enclosed in a suitable ornamental housing 4I.

The extreme outward position of the block 22 is limited by meansof tiemembers 2 I. The down-, ward movement of the gripping plate is likewiselimited by rneans of a stop bar 20 which contacts the back of the slide[6.

While a specific form of the improvement has been described andillustrated herein, it is desired to be understood that the same may bevaried, within the scope of the appended claims, without departing fromthe spirit of the invention.
